🧠 Anatomy & Physiology MCQs – Flashcards

Rationale

Correct Answer: B — Superior

The term superior refers to a structure located towards the head or upper part of the body.

Example: The head is superior to the neck.

Rationale

Correct Answer: B — Inferior

The liver is located below the lungs, therefore it is described as inferior.

Example: The lungs are superior to the liver.

Rationale

Correct Answer: C — Anterior

The sternum is located in front of the heart, which is the definition of anterior.

Example: The rib cage protects the heart anteriorly.

Rationale

Correct Answer: C — Posterior

The esophagus lies behind the trachea, so its position is described as posterior.

Example: Food passes through the esophagus posterior to the trachea.

Rationale

Correct Answer: C — Medial

The ulna is positioned closer to the midline of the body compared to the radius.

Therefore, the ulna is described as medial to the radius.

Rationale

Correct Answer: B — Lateral

The lungs are located on either side of the heart, so their position is described as lateral.

Example: The right lung is lateral to the heart, as is the left lung.

Rationale

Correct Answer: B — Intermediate

A structure located between two other structures is called intermediate.

Example: The clavicle is intermediate between the sternum and the shoulder.

Rationale

Correct Answer: B — Ipsilateral

Organs on the same side of the body are called ipsilateral.

Example: Right arm and right leg are ipsilateral.

Rationale

Correct Answer: C — Contralateral

Organs on opposite sides of the body are called contralateral.

Example: Right arm and left arm are contralateral.

Rationale

Correct Answer: B — Proximal

The humerus is closer to the shoulder joint than the radius, so it is described as proximal.

Example: The elbow is distal to the shoulder.

Rationale

Correct Answer: C — Distal

The phalanges (fingers/toes) are farther from the wrist/ankle than the carpals (wrist bones), so they are distal.

Example: Fingertips are distal to the wrist.

Rationale

Correct Answer: C — Superficial

Structures near the surface of the body are called superficial.

Example: The skin is superficial to the muscles underneath.

Rationale

Correct Answer: B — Deep

Ribs lie underneath the skin, so they are described as deep.

Example: Muscles and bones are deep compared to skin.

Rationale

Correct Answer: B — Lateral

Structures away from the midline of the body are called lateral.

Example: The arms are lateral to the chest.

Rationale

Correct Answer: C — Medial

Structures near the midline of the body are called medial.

Example: The sternum is medial to the lungs.

Rationale

Correct Answer: B — Superior

The heart is located above the liver; “above” corresponds to the term superior.

Example: The head is superior to the neck.

Rationale

Correct Answer: B — Posterior

The esophagus lies behind the trachea, making its direction posterior.

Example: Food passes posterior to the trachea.

Rationale

Correct Answer: C — Distal

Fingers are farther from the point of attachment (wrist) than the wrist itself, so they are distal.

Example: Fingertips are distal to the elbow.

Rationale

Correct Answer: C — Lateral

Lungs are located on either side of the heart, which is the lateral position.

Example: Arms are lateral to the chest.

Rationale

Correct Answer: C — Contralateral

Ascending and descending colons are on opposite sides of the body; this is contralateral.

Example: Right and left arms are contralateral structures.
